actually i just tested the bump and delete method. it actually doesn't make a difference the post stays in the same place as it was before you posted and deleted the post

that is because you deleted the post again. you should post a bump,
and delete all previous bumps, but not the one you just added.

this way you only have 1 bump post in your trade
